Very Unique 1:1 Fire Truck

I stumbled upon this very neat 1:1 Ford F-500 1956 Fire Truck. It was used on U.S. Army Artillery ranges, according to the owner. THis would make a super-cool scratch building project. Also according to the owner, the other 11 of these vehicles have been destroyed... Note: I do not know the owner/seller of this vehicle, and have no interest in the sale. I just think it is a very cool and unique vehicle.
